OF BLOOKINGTON, ILLINOIS, ASSIGIVOR TO MULLINS MANUFACTUR- ING CORPORATION, OF SALEM, OHIO, LA CORPORATION 01' NEW YORK WBINGEB Application filed December 2, 1931. Serial No. 578,451.

The object of my invention is to provide an improved mechanism for readily associating and dissociating the two coacting rollers of a wringer.

The accom )an in drawin illustrates in l. y b D invention in an embodiment suitable for ordinary household use.

Fig. l'is a vertical axial section in partial side elevation;

Fig. 2 an end elevation in partial vertical section just inside the end wall of the base or main frame, and

Fig. 3 a fragmentary end elevation.

In the drawing 10 indicates a main frame or base conveniently formed of sheet metal and comprising hollow and standards 11, oppositely extending aprons 12, guard wings 13 and intermediate trough 14, perforated in its bottom at 1'5.

Each standard is provided, in a common manner, with a vertical guide, open at its the usual-bearing blocks 16 of the lower roller 17, and for the reception of the usual bearing blocks 18 of the upper roller 19.

The above-described construction is wellknown in the art and, in detail, may be varied through a wide range.

The upper end of each standard 11 is open to permit the ready vertical insertion of mechanism, now to be described, carried by the upper cross-head 20. This upper crosshead 20 is conveniently formed of sheet metal and so shaped and proportioned, convenient- 1y, that it may be slightly sleeved over the upper ends of the hollow end standards 11. Secured to the inside of head 20, near each corner, is a bracket 21 into which is threaded the upper end of a bolt 22 which is held in any desired position of axial adjustment, relative to the bracket, by a check nut 23. Sleeved upon each end pair of bolts are the outturned feet 24, 24 of a yoke 25, the middle portion of which lies within the cross-head 20 and forms a receptacle and abutment for one of the bearing blocks 18. Sleeved upon each bolt 22 is a compression spring 26 the lower end of which rests upon the adjacent foot 24 of yoke 25 and. the upper end of which abutsa nut 27 on the bolt.

Pivoted on the end wall of each end standard of the base, at 30, is a link 31 to the upper end of which is pivoted, at 32, one arm 33 of a U-shaped lever 34. The free ends 'of arms 33 project beyond the axisof pins 32 and are notched at 33' to coact with an outwardly projecting pin 36 carried by the cross-head 20 at each of its ends. The links 31 and lever arms 33, in conjunction with pins 36 act as a toggle which, when the parts are thrown from the position shown in Fig. 3 to the positions shown in Fig. 2, serve to anchor the cross-head 20 to the base 10, the parts being so proportioned that, when the toggle is in its medial position, as shown in Fig. 2, the upper roll will be held against separation from the lower roll by the springs 26. Axial adjustment of the bolts 22 permit an accurate co-relation of the parts and when material is injected between the rollers 17 and 19 roller .19 will be displaced upwardly, f yokes 25 moving upwardly and compressing springs 26. Whenever the lever 34 is shifted, to one side or the other of its medial position, the toggle will be quickly broken by the spring pressure and the link will drop out of active position so that the upper roller will then merely rest upon the lower roller and will be freedof all spring resistance.

Readily yieldable latching mechanism of any well-known form (frictional interaction or otherwise) may be provided between the two links of the toggle to normally hold the toggle links in intermediate position against accidental displacement but readily yieldable to application of comparatively slight force laterally to the middle portion of the U-shaped lever 34.

Yokes'25 may either sli freely down over bearing blocks 18 or said caring blocks may be secured to the yokes.

I claim as my invention:

1. A wringer comprising upper and lower frame members, toggle means for connecting said frame members, said toggle means comprising two toggle linkages, one at each end of the structure, one member of each toggle linkage pivotally connected to one frame member and the other element of each toggle linkage separably engageable with the 2 1,oia,e

upper frame member, a connection between the two last-mentioned toggle elements, and spring means carried by the upper frame member. 7 a 2. A wringer comprising a base, a crosshead, a U-shaped lever the free ends of the arms of which are notched, a pair of links each pivoted at one end to an intermediate point of an arm of the U-shaped lever and at the other end to the base, and projections at the opposite ends of the cross-head engageable by the notched ends of the ill-shaped lever.

' 3. A wrinvercomprising a base, a crosshead, a U-shaped lever the free ends of the arms of which are notched, a pair of links each pivoted at one end to an intermediate point of an arm of the U-shaped lever and at the other end to the base, projections at the opposite ends of the cross-head engageable by the notched ends of the U-shaped lever, two abutment yokes for upper roller bearings associated with the cross-head, and spring means interposed between each yoke and the cross-head.

4. A wringer comprising a base, a crosshead, a U-shaped lever the free ends of the arms of which are notched, a pair of links each pivoted at one end to an intermediate point of an arm of the U-shaped lever and at the other end to the base, projections at the opposite ends of the cross-head engageable by the notched ends of the Pct-shaped lever, a pair of depending bolts carried by the cross-head at each end and projectible into the base, a bearing-abutment oke sleeved upon each end pair of bolts, and a spring interlposcd between each bolt and its associated yoe.

5. A wringer comprising a base, a crosshead, a U-shaped lever the free ends of the arms of which are notched, a pair of links each pivoted at one end to an intermediate point of an arm of the U-shaped lever and at the other end to the base, projections at the opposite ends of the crosshead engageable by the notched ends of the U-shaped lever, a pair of axially adjustable depending bolts carried by the cross-head at each end and projectible into the base, a bearing-abutment yoke sleeved upon each end palr of bolts, and a spring interposed between each bolt and its associated yoke.

In witness whereof, I have hereunto set my hand at Bloomington, Illinois, this 21st day of November, A. D. one thousand nine hundred and thirty-one.
